Our Verdict

Corsair K100 RGB

Ducky One 3

The Corsair K100 RGB and the Ducky One 3 are outstanding gaming keyboards. The Corsair is a full-size keyboard available with Cherry MX Speed or Linear Corsair OPX Optical switches. It also has several features the Ducky lacks, including dedicated media keys, a wrist rest, a USB passthrough, an 8000Hz polling rate, and customization software. On the other hand, the Ducky is a full-size keyboard also available in a range of other sizes and colorways. You can purchase it with a variety of stock Cherry MX switches, but it also has a hot-swappable PCB, which means you can use whichever switches you want. Both keyboards have exceptionally low latency, but it's lower on the Corsair.
